New Study: Researchers Invent Mind-Reading Machine that Reads Thought Process

A new study published in the journal Neuroscience suggests that researchers have successfully invented a mind-reading machine that is capable of reading the human thought process.

The research team from the University of Oregon, United States, are said to have developed a system that can read people’s thoughts via brain scans, and rebuild the faces they were visualizing in their heads.

Lead researchers, Brice Kuhl and Hongmi Lee reportedly used artificial intelligence (AI) that analyzed brain activity in an attempt to reconstruct one of a series of faces that participants saw. Tech Worm reports that the result was not exact, but the AI got close.

According to how the machine was able to read the human thought, the researchers created images directly from memories using a Magnetic Resonance Imaging (MRI) machine, machine learning software, and some hapless human test participants.

The researchers then put the test participants in the MRI machine, showing them several hundred faces. The program had access to real-time MRI data from the machine, as well as a set of 300 numbers that described each face. They covered everything from skin tone to eye position.

As the MRI machine detected the movement of blood around the brain, the assumed conclusion was that the movement equals brain activity. The program then analyzed these movements of blood in reaction to the different points, learning how a particular brain reacts to known stimuli.

The AI was then put to the test with a few hundred examples incorporated into its algorithm. The participants were again shown a face, but this time the program did not know anything about the numbers describing it. The only thing it had to go on was the MRI data that described brain activity as the person saw the face. The AI learned to match blood flow over time, which explained the brain activity with facial features seen by the subjects in the MRI machine, spluttering out rough images of what the subjects were seeing.
